**How would you define research? What is the purpose of business research? How may variance and standard deviation be applied to a real-world business-related problem? Provide a specific application in which these measures are useful. When would you use descriptive over inferential statistics? Provide a specific scenario and explain your rationale.**

Research can be described as the process that allows us better understand a topic. The measures of research can be applied to real world applications via hypothesis testing, the test in which you decide if something is increasing or decreasing or is not the same using data and hypotheses, you need the standard deviation for some reason. You would descriptive over inferential when you have data like amount of cans of water consumed per day with a sample of X number of people. It would be better to display the data with descriptive statistics, rather than inferential.
